Application filed October 9, 1905. Serial No. 282,075.

To a/ZZ whom t may concern:

Be it known that we, LUDWIG CHRIST and ALoIs MEGNER, subjects of the German Emperor, residingat Merchingen, near Osterburken, Grand Duchy of Baden, in the Empire of Germany, have invented certain new and useful Improvements Relating to Harvesting- Machines, of which the following is a specification.

This invention relates to a machine for cutting the heads of corn in the field. Its essential novelty consists in the constructionof the cutting device. The latter is composed of three parts a rake, which is arranged at a certain distance above the ground and extends laterally in a horizontal plane; a sawlike knife which moves to and fro between the prongs of the rake in a direction transversely to that in which the machine is driven; and a bar arranged transversely at a certain distance above` the rake and in front All the stalks of corn which arev of the knife. caught by the prongs of the rake are bent down by the bar and prevented from coming in contact with the knife, until, gliding off from the bar, they spring back into their normal position and are forced against the knife which cuts them just beneath the heads of corn.

The drawing illustrates one example of carrying out the invention.

Figure l is a back view of the machine. Fig. 2 is a side view of the same, and Fig. 3 is a plan of the front part of the framework of the machine with the cutting device. is a detail elevation of the trough..

The framework of the machine is composed of a rectangular frame a of T-iron, the rear part of which isI mounted on two ground wheels, and of a flat rail Z) which is attached to the front leg of the frame. Arms c on which is mounted a ground Wheel, is attached both to the rail or bar Z) and to the front leg of the frame. A projecting ledge d to which the pron s of the rake are attached with their lower orked ends, extends over the right half of the bar Z). The prongs of the rake are, as shown in Fig. 2, provided with slits which run from the projecting ledge d and in which the knifef moves. To the right and left of the rake e there are fixed in the projecting ledge d two vertical pegs g which carry supports Zt in 'which rests a bar c' which lies transversely above the rake e and in front Fig. 4

of the knife f, and whose position in relation to these two parts can be regulated as required.

A bevel wheel Zr, which engages with a smaller bevel wheel Z mounted upon a spindle attached to the frame a, is mounted upon the axle of the ground wheels. There is mounted moreover upon the same spindle as the bevel wheel Z a spur wheel 'm which engages with a smaller spur wheel fit-which is also mounted upon a spindle fixed to the frame c. A crank o, which is connected with the sawlike knifef by means of a connecting rod p, is mounted upon the front end of this spindle `which projects beyond the frame a. Behind the rail Z) there is situated a groove r, and between this groove and the frame o, an elevator s. The shaft of the lower cylinder of the elevator is connected with the spindle upon which the wheels Z and m are mounted by chain gear u. A vertical plate o which adj oins the elevator and carries on its bac-k a funnel 'w is arranged on the front leg of the frame a. There are moreover provided on the front leg of the frame two lugs fixed in suitable apertures of the plate o for receiving the pole. f

When the machine is driven, the knife f will be moved quickly to and fro in a direction which runs transversely to that of the machine by means of the wheels Zc Z m and n, the crank o and the connecting rod p, while the endless band. of the elevator s to which cups are attached and which is not shown in the drawing, is actuated by means of the wheels Zr and Z and the chain gear u.

When the machine is driven over a cornfield, the stal-ks of corn which pass between the prongs of the rake e are forced downward by the bar i, and cannot come in contact with the knife f until, the machine moving on, they are released by the bar b, springing back into their normal position, are thrown against the knife. It is now possible by altering the position of the supports h and of the bar i resting therein, so to regulate the position of this bar in relation to the rake and the knife, that the stalks of corn when released by the bar i can only project with their heads above the rake, and must therefore, whether they were originally long or short, upright or bent, be severed in two by the knife just below the heads. The heads which have been cut off fall from the IOC rake which is inclined somewhat toward the rear, into the groove r which inclines to the left, and from thence into the elevator s which lifts them up and throws them into the 'funnel w, from whence they pass into a basket or sack placed beneath it. Two pieces of sheet metal g are 4arranged on both sides of the rake and prevent any corn from falling off it.

What we claim as our invention and desire to secure by Letters Patent is 1. A. machine for cutting the heads of corn, provided with a rake e arranged at a certain distance above the ground and extending laterally in a horizontal plane and having slots in its prongs, a saw-like knife f which moves to and fro in said slots in a direction transversely to that in which the machine is driven and a bari arranged at a certain distance transversely above the ra/ke e and in front of the knife f, which bar bends the stalks of corn which pass between the prongs of the rake and prevents them from coming in*contact with the knife until they are released by it and again assuming their normal position are thrown against the knife, which thereupon cuts them directly below the y heads.

distance above vthe ground and extending laterally in a horizontal plane and having slots in its prongs, a saw-like knilef which moves to and fro in said slots in a direction transversely to that in which the machine is driven, and a bar i arranged at a certain distance transversely above the rake e and in front of the knife f, which bar bends the stalks ol corn which pass between the prongs of the'rake and prevents them from coi'ning in contact with the knife until they are released by it and again assuming their norm al position are thrown against the knife, which thereupon cuts them directly below the heads, and a trough lying behind the said rake and inclined downward away from the rake, which. latter is also inclined downward toward the rear, and an elevator arranged in proximity to said trou h and a funnel provided adjacent to said e evator, substantially as described.

In testimonyvwhereof we have hereunto signed our names to this specification in the presence of two subscribing witnesses.
